Officers declined to identify the man pending his arrest, and that might not come until after he is discharged from the hospital in the coming days, according to Mobile Police spokesman Chris Levy.

Investigators combing through the charred remains of the fire discovered the meth labs inside the structure, though they initially said the potentially explosive operation apparently did not ignite the blaze.

According to information released on Saturday, firefighters responded to a house fire at about 11:06 a.m. at 7670 Garden Grove Drive to find smoke pouring from the single-story wooden structure. Medical responders on the scene found the 39-year-old man with burns over 70 percent of his body sitting on the porch.

Officers said the man was transported to the University of South Alabama Medical Center, where he was undergoing treatment for second- and third-degree burns, according to the release.

Investigators initially said the fire appeared to have started when malfunctioning electronics equipment ignited clothing piled above. Officers said they believe the man was sleeping nearby when the fire began in the bedroom, and unsuccessfully tried to extinguish the blaze when he awoke.

Levy said officers recovered 7 grams of a powdery substance believed to be methamphetamine, and 80 grams of a liquid believed to contain methamphetamine.

Damage from the fire was estimated at $30,000, and no other injuries were reported, according to the release. An investigation into the fire was continuing on Saturday.

Mobile Fire-Rescue spokesman Steve Huffman said his agency did not release the names of people involved in incidents, and referred further questions to Mobile Police.

Levy said the man’s name would not be released until his arrest. Charges the man will likely face include unlawful manufacture of a controlled substance, trafficking methamphetamine and possession of drug paraphernalia.
